If this were true, then having 4 HXs in parallel would give you 4x the BTUs, and having 8 HXs in parallel would give you 8x the BTUs, etc. and eventually your BTU output would exceed the available heat energy.
Will not happen, violates the laws of physics.
When you run 2 HXs in parallel, you are reducing your resistance
only because you are reducing the velocity of fluid flow through each HX.
Reducing the velocity reduces the BTU output.
You will have an increase in efficiency but nothing like 2X.
